Headphones making volume decrease automatically

Just found a weird issue with my priv, when using my ear buds the volume randomly will go all the way to zero by its self, and when I try to increase the volume it fights me and goes down while I'm trying to turn it up. The brand of headphones is skullcandy and I have 2 pairs that do the same thing. I tried some samsung ones and they didn't have the problem but they sound worse and do not get nearly as loud. I need them loud because when I play my drums I need to hear the music which I can't with the Samsung ones. Anyone else have this issue? I would hate to have to buy new ones as i like the ones I already have.

Headphones partially not working - not a hardware issue

Hey fellas,

so I recently got a used S6 Edge and there was a problem whenever I used headphones. The left earbud works fine but there is hardly any sound coming out of the right one(checked with several headphones, its a phone issue), really just minimal, very very quiet. I naturally figured this was a hardware error so I went to my local phone repair guy and had that part replaced.
Now, unfortunately the problem still isn't solved. With the new replacement it has gotten a little bit better, but the right earbud is still a lot quieter than the left one. So the repair guy said its a software issue.
Do you guys know anything about that?
I'm not rooted and on the official 5.1.1. Just tried factory resetting but that didn't really help. Any suggestions or anything I can look into that might solve this issue, be it rooted or not?
Cheers
